Rigid spine syndrome caused by a novel mutation in four-and-a-half LIM domain 1 gene (FHL1).
Four-and-a-half LIM domain 1 gene (FHL1) has recently been identified as the causative gene for reducing body myopathy (RBM), X-linked scapuloperoneal myopathy (SPM) and X-linked myopathy with postural muscle atrophy (XMPMA). Rigid spine is a common clinical feature of the three diseases. We searched for FHL1 mutations in eighteen patients clinically diagnosed as rigid spine syndrome (RSS). We identified one RSS patient with FHL1 mutation. Reducing bodies were observed in few fibers of the patient's muscle sample. Amount of FHL1 protein was decreased on immunoblotting. In conclusion, FHL1 can be one of the causative genes for RSS.
